In past generations, singing and playing instruments was an integral part of family life. A great way to express and entertain yourself and others. We did not realize it, but we were also exercising our brain while we played, causing us to be creative, more vibrant, smarter, etc. In our current generation, we tend to be passive listeners and consumers as a society, and as a result, shorting our mental development and our children the opportunity to reach their mental potential.
